Keeper of the Meaning

Keeper of the Meaning is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Keeper of the Meaning rather than just read about it. In short: Keeper of the Meaning is a stage of adult development which involves the "conservation and preservation of the collective products of mankind". This stage was developed by George Vaillant in 1993 and added to Erikson's stages of psychosocial development, between generativity vs. stagnation and integrity vs. despair.

Key takeaways

Keeper of the Meaning belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Keeper of the Meaning to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Keeper of the Meaning from memory before moving on to harder problems.

Reference excerpt

Keeper of the Meaning is a stage of adult development which involves the "conservation and preservation of the collective products of mankind". This stage was developed by George Vaillant in 1993 and added to Erikson's stages of psychosocial development, between generativity vs. stagnation and integrity vs. despair. This stage covers the ages of 60 to 75. Vaillant contrasts keeper of the meaning with rigidity. Vaillant stresses that wisdom is a central part of the keeper of the meaning stage. Where generativity focuses on the care of individuals, keeper of the meaning is less selective and focuses on wisdom and justice.

Worked examples

Example 1 — a first encounter with Keeper of the Meaning

Start with the simplest possible case. Write down what Keeper of the Meaning claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Keeper of the Meaning before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Keeper of the Meaning ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Keeper of the Meaning

In research: Keeper of the Meaning appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Keeper of the Meaning in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Keeper of the Meaning is common in secondary-school and first-year university syllabi. It links to neighbouring topics Developmental psychology, so understanding it makes those chapters shorter.
In everyday life: Look for Keeper of the Meaning outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
